Recent official forecasts from the Met Office and European models indicate London’s minimum temperature on September 18 will most likely fall between 11°C and 12°C overnight into early morning, driven by light westerly winds, variable cloud cover, and moderate radiative cooling under Atlantic air masses typical for mid-September. These conditions favor modest overnight drops without strong cold advection or clear-sky extremes, aligning with climatological norms for the season. Ensemble guidance shows limited spread around this range, supporting the market’s heavy weighting toward 11–12°C outcomes while assigning low probability to colder or warmer extremes that would require atypical model shifts. Updated model runs and Met Office briefings through September 17 have reinforced this consensus ahead of the day’s resolution.

The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=eglc
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
